wait_event_interruptible_timeout() will return early if the blocked
process receives a signal, causing the driver to abort the tuning
procedure and possibly leaving the controller in a bad state. Since the
tuning command is expected to complete quickly (<50ms) and we've set a
timeout, use wait_event_timeout() instead.

The mmc block queues are kernel threads which I would expect ignore signals,
so I am curious how you hit this?
The issue was discovered on (tegra2?) hardware that is sensitive to
being interrupted during tuning and having the controller left in a
sensitive state.
@Christopher Freeman: Maybe you can provide us with some additional details?
In any case:
